It seems the review used the Gigabyte E350N-USB3 which has probably the highest power consumption for any E350 based motherboard.
Even xbitlabs said it had very high power consumption:

"The thing is that we used Gigabyte E350N-USB3 mainboard to measure the performance of Brazos platform in our today’s test session. And this mainboard wasn’t designed with power-efficiency in mind, and its power consumption is significantly higher than it could have been, had the developers really paid special attention to this aspect. One of the good examples could be the recently reviewed MSI E350IS-E45 mainboard, which power consumption in idle mode was only 7.3 W. It means that good AMD Brazos mainboards can in fact beat Core i3-2100T in idle mode when it comes to energy-efficiency."
However,the much cheaper MSI E350IS-E45 in this article consumes far less power:

It consumes 7.3W at idle,15.8W during a CPU load and 17.5W during a GPU load and 14.9W during 1080p playback.
The Celeron G440 consumes 15.5W at idle,21.7W during CPU load,26.8W during GPU load and 21.9W during 1080p playback.
Regarding the Intel T series processors they are basically standard processors with the clockspeed reduced to fit the lower TDP. Idle power consumption and power consumption during media playback is not that much different than the higher clocked processors in the range. For instance I was looking at undervolting my Core i3 2100 and it seems that the Core i3 2100 can be modified to have similar power consumption to a Core i3 2100t by reducing the clockspeed.
